The standard audiological protocol utilizes quiet measures. However, it has been noted that speech recognition in noise (SRN) testing provides information that cannot be inferred from quiet measures.
The purpose of this convergent validity study was to investigate the relationships between behavioral responses in quiet and in noise.
Bilateral pure-tone averages (BPTA) were calculated for thresholds from 500 to 6000 Hz. The Hearing in Noise Test (HINT) thresholds in quiet (HINT-Q) were also measured. SRN performances were determined using the HINT Noise Front (HINT-F) condition and the AzBio test. The HINT-F uses steady-state speech-shaped noise and the AzBio uses a 10-talker babble. All conditions were randomized.
Fifty young, native English-speaking females with pure-tone thresholds less than or equal to 25 dB HL participated in this study. The average age of the participants was 20.5 years (standard deviation = 1.47).
Pearson correlation coefficients were used to quantify the relationships between all measures.
Statistically significant relationships were found between HINT-Q thresholds versus BPTA (r = 0.62, < 0.01) and between HINT-F thresholds versus AzBio (0 dB signal-to-noise ratio) scores (r = -0.41, < 0.05). No significant relationships were found between any of the quiet versus noise measures.
These results suggest that, for individuals with pure-tone thresholds less than or equal to 25 dB HL, SRN ability must be measured directly and not inferred from PTA or speech-in-quiet measures. It is possible, to a modest degree, to predict AzBio performances from the HINT-F thresholds, and vice versa.
标准听力学方案采用安静环境下的测量方法。然而，人们已经注意到，噪声中的言语识别（SRN）测试提供了从安静环境下的测量中无法推断出的信息。
本收敛效度研究的目的是调查安静环境和噪声环境下行为反应之间的关系。
计算500至6000赫兹阈值的双侧纯音平均值（BPTA）。还测量了安静环境下的噪声听力测试（HINT）阈值（HINT-Q）。使用HINT噪声前沿（HINT-F）条件和AzBio测试来确定SRN表现。HINT-F使用稳态言语形状噪声，AzBio使用10人嘈杂声。所有条件均随机安排。
50名母语为英语的年轻女性参与了本研究，其纯音阈值小于或等于25分贝听力级（dB HL）。参与者的平均年龄为20.5岁（标准差=1.47）。
使用Pearson相关系数来量化所有测量之间的关系。
发现HINT-Q阈值与BPTA之间存在统计学显著关系（r = 0.62，<0.01），以及HINT-F阈值与AzBio（0分贝信噪比）分数之间存在统计学显著关系（r = -0.41，<0.05）。在任何安静与噪声测量之间均未发现显著关系。
这些结果表明，对于纯音阈值小于或等于25 dB HL的个体，必须直接测量SRN能力，而不能从纯音听阈（PTA）或安静环境下的言语测量中推断。在一定程度上，可以根据HINT-F阈值预测AzBio表现，反之亦然。
